Simple and high-performance coupling for higher speed/larger capacity This diaphragm coupling originally developed for helicopter drive shafts has been redesigned for general industrial purposes. The diaphragm part employs a special profile processing (characterized by high torsional rigidity, flexible against bending/compression) to achieve high torque transmission. This product has marked a maximum speed of 100,000 rpm and maximum torque of 2,700 kN-m in actual applications, and has gained good reputation in various fields as an ideal coupling (i.e. high speed/high load torque transmission, light weight, and no lubrication). Characterized by the capacity to flexibly absorb misalignments (low bearing load), this diaphragm coupling has been increasingly recognized to be essential for turbines and compressors of ever higher speed/larger capacity, as well as other rotating equipment for commercial power generator, steelmaking machines, equipment for vessels, and aircraft, etc.
Rotary Joint for Semiconductor Application
This is an epoch-making compact cartridge type rotary joint incorporating a mechanical seal. Optimized design enables low torque joint. The rotary joint is used for CMP (Chemical Mechanical Polishing) or lapping equipments which polish wafers in the production process of semiconductors.
V-Flange joints could provide reliable connection point for ease of installation/removal of ducts and attached equipment ( eg, valves). A single faster coupling for quick assembly and removal is available. Snap fit enables, replaceable metal seal for low leakage and ease of installation. Many type of materials are also available in machinable alloys such as stainless, nickel, titanium, and aluminum. Three off the shelf ratings are provided: Micro, Low and Standard to meet a wide range of conditions ( including AS1895)
Ducting Components and System
Typical applications include turbine engine bleed air and cooling ductings, engine exhaust, and other extreme temperature/pressure rely on our great systems. Air-worthiness is critical as the failure could lead to dangerous condition. Design also requires compatibility of very light weight and robust construction cause of aerospace application. EEA could offers complete duct system design, test and manufacture. Our technology base is supported by previous EG&G Pressure Science Inc. ( Presently Perkin Elmer Inc.).
Tube Seal Joint
EEA’s flexible ducting joints are based on a unique high temperature metallic seal which we call the “Tubeseal”. The Tubeseal is a precision formed metallic seal with a spherical end which is in elastic compression in a cylindrical bore. It is capable of sliding, rotating, and angulating in that bore with leakage rates about two orders of magnitude lower than can be achieved with the very best of piston rings. Tubeseal could provide virtually unlimited axial sliding capability, without high loads or fatigue problems. Rotational freedom, if desired. We could design extremely compact pressure compensated flex-slide joints, if requested.
Bellows Ducting Joint
Metal bellows ductings could provide angular movement to accommodate installation, thermal and dynamic duct deflections. Zero leakage improves efficiency and reduces operating costs. Controlled bending moment for predictable system life and reduced loads on fixed points ( such as engine ports) Bellows ductings could provide optimized bellows design for longer life and shorter, lighter bellows. Flow liners provide lower pressure drop and eliminate flow resonance.
